The component identified as in modern schematics is a resettable PTC fuse (PolySwitch), typically rated for 1.1A and 24V

Ensure the wiring between the primary device and the IM-T-11A is protected against shorts to other power sources. Fuse Protection: f4901 11a 24v schematic top

The "top" view of the schematic also highlights the integration of the load. In an 11A system, the load could range from a heavy-duty DC motor to an array of high-intensity LEDs or a heating element. The schematic illustrates how the load is isolated from the control logic, often via optocouplers if the design includes an isolation stage. This separation is a hallmark of 24V industrial systems, protecting sensitive microcontroller logic from the noise and potential surges of the high-power side.

The PCB is covered with small black chips labeled with codes:
